"One way to scam people is to diagnose and correct a nonexistent problem. Aqua Detox practitioners do this by claiming to remove toxins and balance cellular energy. During treatment sessions, the customer's feet are bathed for 30 minutes in salt water that is subjected to a low-voltage current transmitted through an electrode assembly called an "array" (the dark cylindrical object to which the wire is attached). Aqua Detox International claims that the apparatus "produces a frequency of positive and negative ions, which gently resonates through the body and stimulates all the cells within it. . . . rebalancing the cellular energy, enabling the cells to perform efficiently and . . . release any toxins that may have built up." During the process, the water typically turns reddish brown. Some marketers refer to the process as "ionic cleansing" or an "ionic foot bath."….. Positive and negative ions cannot "resonate" throughout the body in response to any such device. And the skin has no ability to excrete toxins. Real detoxification of foreign substances takes place in the liver, which modifies their chemical structure so they can be excreted by the kidneys which filter them from the blood into the urine."
